Replacing your existing Vaillant boiler is something you should do every 10-15 years. As time goes by, boilers get less and less efficient meaning that the water is not always as hot as you want it to be, your boiler has trouble supplying the radiator with what it needs, and your utility bills go up. What are Valiant boiler prices in 2018, what choice of Vaillant boilers are available, and how much does a typical Vaillant boiler installation cost?
We work with over 100 different Gas Safe Registered Vaillant boiler installers across the UK and we asked them to provide us with the cost of a Vaillant boiler together with example quotes on how much it would cost to get a new Vaillant boiler installed where it is now in your home or in a different location. This is what they came back to us with:
|Supply only||Where it is now||A new location|
|Vaillant combi boiler||£885-£1,305||£1,885-£2,305||£2,285-£2,705|

Of course, these are sample quotes. You may pay more or less, depending on the complexity of replacing and installing your new Vaillant boiler. Bear in mind too that the more complex your installation, the longer it will take.

Vaillant combi boilers
Combi boilers are the most popular type of boiler in the UK. Around two thirds of homes have them and nearly all new-build homes and flats have them too. All your hot water and central heating is provided by a small, compact central unit which can be hidden from view in a kitchen cupboard. No hot water tanks and no hot water cylinders are required.
It’s important that, with a Vaillant combi boiler, your installer gets the maximum flow rate just right so that more than one tap can be used at a time without affecting the pressure of the water being delivered. In the past, many homes have been fitted with a boiler whose maximum flow was less than it needed to be. The technology behind combi boilers has improved significantly in the last decade so this is not the problem it used to be.
Combi boilers are cheaper to install than other types of boiler because the amount of pipework and related labour costs is a lot less.
Vaillant’s current range of combi boiler prices and specifications is below:
|ecoTEC Pro 24||720||440||335||9.4 l/min||24 kW||B||86-90%||£885|
|ecoTEC Plus 824||720||440||335||9.4 l/min||24 kW||B||86-90%||£965|
|ecoTEC Pro 28||720||440||335||11.5 l/min||28 kW||B||86-90%||£875|

Vaillant heat only conventional boilers
Heat only (often called conventional) boilers are more suitable for larger properties with two or more bathrooms (family or en suite), with old-fashioned radiators, in low water-pressure areas, and for when a family needs to use a lot more hot water than an average family needs.
Vaillant conventional boilers require both a cold water tank in the loft and a hot water cylinder in the airing cupboard. Installation takes much longer for a conventional boiler and this is generally reflected in the overall price of your replacement work.
Vaillant currently have four conventional boilers, the prices for and specifications of which you can see below:
|ecoTEC Plus 415||720||375||340||N/A||15 kW||B||86-90%||£795|
|ecoTEC Plus 418||720||375||340||N/A||18 kW||B||86-90%||£870|
|ecoTEC Plus 428||720||440||335||N/A||28 kW||B||86-90%||£985|
|ecoTEC Plus 438||720||375||340||N/A||38 kW||B||86-90%||£1,430|
Vaillant system boilers
Vaillant system boilers also have a hot water cylinder, just like their conventional boilers, but they do not need a cold water storage unit to work. The hot water cylinder in a system boiler installation not only stores and distributes the water – it also contains all the hot water and heat generation parts in it too.
When should you consider a system boiler? If you want to supply hot water at exactly the same pressure to as many taps as you want at once (particularly useful if you have more than one bathroom), you should ask your installer about the pros and cons of a Vaillant system boiler in your situation.
Please find below Vaillant system boiler prices together with the specifications for each system.
|ecoTEC Plus 612||720||440||335||N/A||12 kW||B||86-90%||£825|
|ecoTEC Plus 615||720||440||335||N/A||15 kW||B||86-90%||£865|
|ecoTEC Plus 618||720||440||335||N/A||18 kW||B||86-90%||£960|
|ecoTEC Plus 624||720||440||335||N/A||24 kW||B||86-90%||£1,080|
|ecoTEC Plus 630||720||440||335||N/A||30 kW||B||86-90%||£1,190|
|ecoTEC Plus 637||720||440||335||N/A||37 kW||B||86-90%||£1,255|
Vaillant boiler size output rates
The output rate of a Vaillant boiler measures how capable your boiler is of heating up water to the required temperature before it comes out of your kitchen or bathroom taps.
Your installer will calculate the maximum amount of water you need at any one time and, from that, they work out the amount of output (measured in kilowatts) that your boiler needs to generate to heat that water quickly enough so that you get water at the right temperature at the right time.
Vaillant boiler size maximum flow rates
How many taps are turned on at any one time in your home? If you’ve lived in a home before where the boiler could not deliver the right amount of water needed, you may have experienced the problem that causes when you went for a shower and someone turned the kitchen tap on. Suddenly, the power shower you were having stutters a few times. Too much demand for water affects both the pressure of the water coming out of the showerhead and the blend between the hot and cold water.
Your installer will try to calculate the “maximum flow rate” of your Vaillant boiler replacement so that all the water gets to the taps and the showers needed without a drop in pressure.
Vaillant boiler size energy efficiency
There are no current Vaillant boilers that are “A” rated for energy efficiency. However, their entire range is currently B-rated offering a very impressive 86-90% energy efficiency. That means that 86-90% of the gas your Vaillant boiler uses goes directly to providing hot water and your central heating.
This means that you won’t achieve quite the savings shown above but they won’t be far off the true savings you make every year.
What about reputation?
Vaillant have been trading for over 140 years and supply customers in over 60 countries. From small beginnings, it’s now an international company, still family-owned, and their main area of business is still manufacturing and supplying boilers. It’s recently expanding into both the air-conditioning and ventilation markets as well.
Klaus Jesse, managing director of Vaillant UK and Ireland, states that he and his colleagues are constantly driven to provide industry-leading customer services and training services and that the hallmark of the business is that, even in the age of the internet, it is still powered by customer referral and recommendation.
How do they deal with customers who are not happy?
Vaillant runs dedicated customer services and complaints teams from its base in Belper in Derbyshire. Customers can complain directly to the company by using this page on their internet site.
Vaillant achieves and maintains very high customer satisfaction on online review sites with a score of 8.6 of out 10 on TrustPilot based on over 3,800 reviews.
How about the warranty?
Vaillant’s call centre operates 24 hours a day across 364 days of the year. They’re available at nearly any time to arrange a local service engineer to call around to customers’ homes.
When an engineer is at a customer’s home, they’re able to fix 98% of all issues on their first visit. There are 250 service engineers in all corners of the UK who carry 95% of all spare parts of their vans. They offer a homeowner technical help line specifically to assist customers in understanding the user guides so that they get the most out of their new boiler system.
Warranties on their products last from two to five years. They are able to extend many customers’ warranty periods free of charge if they decide to choose a Vaillant-approved company to carry out the installation.
And once you have your boiler, don’t forget about boiler cover.
